'WASHING CHINE.

pplicaton ledll'uly 22, 1925. Serial No. 45,283.

My invention relates to washing machines and more particularly toimprovements in lwashing machines of the dolly type.

The usual types of washing machines are s Classifiable according to therelative action of the dolly upon the fabrics and upon the liquid,respectively. In the rst class, ma-

chines having a peg type of dolly effect merely a swirlin movement offabric io through the liquid, resulting 1n excessive strain and wear in`the cloth being washed. ln the second class, the result is effectedprimarily by agitation of the liquid. Familiar examples of this classare found in i the vacuum cup machines, and in those utilzing thecapillary eifects common to 'the old fashioned scrubbing board. A thirdclass of machine combines the. operations of the preceding types. Thecylinder ma- 2o chines, which lift the fabrics and ldrop them back intothe liquid, are good examples of this third or combination class. lt isevident that each of these type is peculiarly adapted to thev mosteiiicient washing of only certain restricted classes of materials.

The object of my invention is to provide agitating means which comprisesa novel form of removable, invertible agitator and which may be adjustedin its position with A respect to the materials to be washed, therebyproviding in one machine, means for washing most efficiently any type offabric.

Another object is to provide an agitator with its drive and mountingwhich cannot,

tear the clothbeing washed.

Further objects and advanta es of my invention will appear from therawings and description thereof as hereinafter set forth.

Although my invention consists lar ely in the construction andarrangement o parts hereinafter described and particularly pointed outin the claims, yet I do not limitvmy invention to the precise form orconstruction of parts shown or the several parts thereof, inasmuch asvarious alterations may be made without changing the scope of myinvention. In the drawing, Fig. 1 represents a top view of the operatingdolly of the washing machine: Figs. 2, 3, and 4 show the doll in variousoperative ositions.

Referring y numerals to the drawings, the tub-base 10 preferably restsupon a substructure made of angle bar or other suitable material. Thetub is preferably composed of a heavy sheet metal body 11 which -may beof'any desirable ,shape and which is preferably provided with 'aninwardly extending turned-over upper edge 11 and a flange 10 on itslower edge. Tub body 11 with its turned over edge 11,l and flange 10 e0may be readily formed from a iiat sheet of material, thereby providingease and economy in manufacture. Tub base 10, which may be die formed,ispreferably united vto the inside surface of flange 10 by a welded e5or other joint in such. a manner that the inside surface of the tubstructure presents no ragged edges, seains or projections. This insidesurface is preferably tinned or other- Wise coated, a'ording a rustproof surface, 7o thus permittingthe use of steel orother comparativelyrigid material in the tub construction, and which coating material willvfurther provide a means of filling any interystice which may exist atthe tub joints. By I the use of this type of joint, the gaugevof thesheet metal is not limited as in the usual constructions using doubleseam joints, orfin the case of forming the tub by spinning or othermethods. Preferably integral with the so base 10 is the agitator Well orpedestal 13'v whichinay be attached in any suitable inanner and ispreferablyv centrally situated therein. Connection with'the drivingmechanism is preferably effected through Well 13 85 *l by means of anagitator sleeve 14. This lat-v ter is preferably rotatably mounted onthe stationary agitator Well or pedestal 13 and rotates on bearings 15and 16 which may be' of any suitable type. The sleeve 14 prefer- 90 ablyextends the full length of its support to the bottom ofthe tub so thatin rotation there is no tendency for the clothes to tear because ofrelative movement between the sleeve and well. The lower end 14 of the95 sleeve 14 is preferably fiared to divert fabrics from the center to'the sides of the tub andtlius provides a natural course of movement ofboth clothes and water. rlhe agitator 17 is preferably mounted onagitator sleeve 14 100 and in such a mannerias to be driven by it and tobe easily lifted from the sleeve to permit inversion of position of theagitator and its removal Whenever necessary. The agitator 17 preferablyconsists of a disc- 105 like structure, an approved form of which isshown in the drawings. 18 represents a preferable forni of relativelythin blades on one operating surface or face of the agitator and 19represents a preferable forni R10 of relatively angular projections ontheV reverse surface.

When large Aheavy fabrics are to be washed, the blades l18 arepreferably placed upon the top of the. material, giving agitation ofboth cloth and liquid.' If hea small piece fabrics are in themachine, te agitator yis lifter from the sleeve A and replaced with its reverseprojections 19 Y above the bottom as will be determined by4respectively, the agitator being supported downward, providing only -aslight move- `ment of materials suliicient to change their the natureand amount of material to be washed. If the agitator be left in thebottom of the receptacle with its blades 18 up"-v ward and thematerialsimmersed labove, it,

only liquid agitation results. This latter arrangement is best suited tolight delicate' fabrics. The three suggested ositions of the agitator 17with respect to t e materials to be washed are shown in Figs. 2, 3 and4- above the bottom of the tub, in certain cases, by the materials beingwashed. In Figs. 3 and 4 the agitator is shown in the posltion which itwould occupy when resting upon the material to be washed. Other combina-A tions of agitator design and position may be par'al el to or at rightangles to each other, 40

' type of clutch used.

While I show the projections and blades on the agitator surfaces asbeing at approximatel right angles to these surfaces, and

the angle between said blades and said surfaces, or between differentblades, may be varied in any way. Further these projections or bladesmay beveither flat orl cambered. Holes 20 are perferably provided in theagitator to produce a better circulation and agitation o liquid, and topermit passage of the liquid through the agitator.

The agitator 17 and sleeve 14 are preferably given an oscillatingmovement by means of shaft 21, preferably to the upper end 'of whichsleeve 14 is secured by a pin' 36, or by a nut or other means. Below thetub on shaft 21 is preferably fitted some suitable (not shown) actuatedby a clutch control, preferably permitting the engagement ordisengagement of a. pinion with a rack' of suitable type bythereciprocation of which the shaft is given an oscilating movement. l

' I claim:

v1. In a machine for washing fabrics, an invert-ible agitator disk,having a plurality of operating faces, each of said faces belng adaptedfor a predetermined use.

2. In a washing machine, aremovable invertible agitator disk, having aplurality of operating faces, and means whereby `said faces may beadjustably positioned with respect to the material to be washed.

3. In a washing machine, a removable invertible agitator disk, havingrelatively flat angular projections onone face thereof and 'relativelythin blades on another `face thereof.

4. In a washing machin-e, a removable inlvertible agitator disk, havingrelatively flat angular projections on one face 'thereof and relativelythin blades on another face thereof, and means for adjustably mountingsaid agitator whereby said projections and blades may be selectivelypositioned with respect to the material to be washed.

5. In a washing machine, a container, an agitator sleeve adapted to bemovably mounted within said container, and a removable invertibleagitator disk, havingv vertically opposed impelling members and adaptedto be adjustably positioned on said sleeve. j

6. In a washing machine, a tub, a pedestal adapted to be mounted withinsaid tub and attached thereto, an agitator sleeve adapted to berotatably mounted on said pedestal,

I'and a removable invertible agitatorv disk comprising va variety ofimpelling means and adapted to be adjustably positioned on said sleeveand to rotate therewith.

`7.A In a washing machine, a tub having an opening through the -bottomthereof, a hollow pedestal adapted to be mounted within4 said tub oversaid opening, a shaft adapted to operate through said opening andpedestal', an vagitator sleeve adapted to be removably positioned aboutsaidpedestal, a bearing between said sleeve and said pedestal,connecting means -between said shaft and said sleeve, and a removableinvertible agitator disk, having a itating elements on opposite faces,and adapted to be adjustably positioned on said sleeve and to rotatetherewith.
